Sapper army

Type of Red Army engineer formation during WW2

A Sapper Army was a multi-brigade military construction engineer formation of the Engineer Troops of the Soviet Red Army during World War II. Formed to construct large-scale defensive works, sapper armies were used from late 1941 until mid-1942 when the Red Army opted to organize smaller and more flexible construction engineer formations. Although the organization of military construction engineers into an army-level echelon was unusual, the use of dedicated troops for military construction was common to many armies of World War II.
